I am writing an algorithm that finds the center of 500 x 500 pixels images coming from a live feed from a camera at 50 Hz. So it has to be quick! The images are images of an optical field which looks ...

SMALL UPDATE: This question is left as unanswered, because none of the existing answers as of yet actually use CUDA (though, whilst being very useful).

To make it a bit more clear, and ...

Sparse arrays are widely used in many scientific applications where memory and time are strictly limited. For a considerable speedup one can use CUDA. Since Mathematica 8 we can conveniently use CUDA ...

We have iMac desktops and have just begun to parallelize computations across them see: Wolfram Light Weight Grid and parallel computing.
This still does not look like it will give us the performance ...

In a project of Monte Carlo Modelling of Grain Growth (Link) one of the most costly subroutines is the calculation of the Potts-Energy of an Monte Carlo Grid cell by comparing the center cell value ...

CUDALink is properly installed and up to date, all built-in functions work fine, and all little functions I did worked fine... Until I tried using shared memory.
The only example I found on the help ...

I have set up a Mathematica remote kernel on a Windows 7 64 bit machine, which has Microsoft Visual Studio 2010 installed. When I start Mathematica on the windows machine Mathematica recognizes the ...

The GPU memory manager documentation is not too clear, does GPU memory leak if not explicitly unloaded or if the symbol that holds the reference to the GPU memory gets collected, the GPU memory gets ...

In an attempt to answer my own question (Beginner CUDA: two dimensional blocks and two dimensional threads?).
Please excuse the long post, it contains for examples I constructed as an experiment to ...

This is a follow up question to: CUDA: setting grid dimensions. The purpose of the question is to understand how Mathematica is interfacing with CUDA's architecture. I have a related question/request ...

I have Mathematica 8.0.4.0 installed on my new MacBook Pro running OS X 10.8. I also have the latest CUDA drivers (and even the CUDA SDK) from nVIDIA. I've noticed that commands like CUDAQ[] take a ...
